SPMWH1221FD7GBTMSA LED Equivalent & Substitute Parts

Part Overview

The SPMWH1221FD7GBTMSA is a surface-mount LED from Samsung Semiconductor's LM282B series, specified for neutral white lighting applications at 4000K color temperature. This component is classified as "Not For New Designs," indicating it has reached end-of-life status in Samsung's product portfolio. Organizations currently using this part in production or maintenance applications require documented equivalent and substitute options to ensure supply chain continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1221FD7GBTMSA is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Series: LM282B
• Color: White, Neutral
• CCT: 4000K
• Forward Voltage (Vf): 6.3V
• Test Current: 150mA
• Maximum Current: 160mA
• Luminous Flux @ 25°C: 110lm (105–115lm range)
• Luminous Efficacy: 116 lm/W
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• Size / Dimension: 3.50mm × 2.80mm
• Height – Seated (Max): 0.75mm
• Thermal Resistance: 15°C/W
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Variable Parameter (Allows Substitution Variance):

• Color Rendering Index (CRI): The main part specifies CRI 90; substitute parts with CRI 80 are functionally equivalent within the LM282B series specification range.

All three substitute parts meet these criteria and are therefore direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—SPMWH1221FD5GBT0SA, SPMWH1221FD5GBTMSA, and SPMWH1221FD7GBT0SA—are parametric equivalents of the SPMWH1221FD7GBTMSA within the LM282B series specification framework.

Selection Criteria Based on Provided Data:

1. CRI Requirement: If application specifications mandate CRI 90, select either SPMWH1221FD7GBTMSA or SPMWH1221FD7GBT0SA. If CRI 80 is acceptable, SPMWH1221FD5GBT0SA and SPMWH1221FD5GBTMSA are suitable alternatives.

2. Packaging Designation: The suffix variation (FD5 vs. FD7, GBT0SA vs. GBTMSA) reflects internal Samsung packaging or tape configuration differences. Both packaging types are Tape & Reel (TR) format and are mechanically and electrically interchangeable.

3. Inventory Availability: Current stock levels are SPMWH1221FD7GBTMSA (49,017 pcs), SPMWH1221FD7GBT0SA (44,233 pcs), SPMWH1221FD5GBTMSA (34,900 pcs), and SPMWH1221FD5GBT0SA (16,508 pcs).

4. Compliance: All parts are RoHS Compliant with MSL 2A (4 Weeks), meeting standard industrial handling and storage requirements.

5. Product Status: All parts carry "Not For New Designs" status, indicating end-of-life classification. For new product development, alternative current-generation LED solutions should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1221FD5GBT0SA replace SPMWH1221FD7GBTMSA in existing designs?

A: Yes, SPMWH1221FD5GBT0SA is a parametric equivalent. The primary difference is Color Rendering Index (CRI 80 vs. CRI 90). If the application does not specify CRI 90 as a requirement, this substitute is electrically and mechanically compatible. Verify application CRI tolerance before substitution.

Q: What do the suffix codes (FD5, FD7, GBT0SA, GBTMSA) indicate?

A: These suffixes represent Samsung's internal packaging and tape configuration designations. Both FD5 and FD7 variants, and both GBT0SA and GBTMSA packaging types, are functionally equivalent 2835 metric package LEDs in Tape & Reel format. The differences do not affect electrical performance or mechanical fit.

Q: Are all substitute parts in the same 2835 package?

A: Yes. All parts—SPMWH1221FD7GBTMSA, SPMWH1221FD5GBT0SA, SPMWH1221FD5GBTMSA, and SPMWH1221FD7GBT0SA—use the 1113 (2835 Metric) package with identical dimensions (3.50mm × 2.80mm) and maximum seated height (0.75mm). They are pin-compatible and PCB-compatible.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates that Samsung has discontinued active development and long-term support for the LM282B series. While existing inventory remains available for current production and maintenance, these parts should not be selected for new product development. Organizations should evaluate current-generation LED alternatives for new designs.

Q: Are there any thermal or performance differences between the substitute parts?

A: No. All substitute parts share identical thermal resistance (15°C/W), forward voltage (6.3V), test current (150mA), maximum current (160mA), luminous flux (110lm at 25°C), and luminous efficacy (116 lm/W). Thermal and electrical performance are equivalent across all four part numbers.

Q: What is the MSL 2A (4 Weeks) requirement?

A: Moisture Sensitivity Level 2A indicates these components must be stored in dry conditions and used within 4 weeks of opening the original packaging. Standard industrial moisture-barrier packaging and controlled storage conditions satisfy this requirement.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All four part numbers are parametrically equivalent and can be used interchangeably within the same assembly. However, if CRI consistency is critical for the application, segregate parts by CRI rating (90 vs. 80) to maintain color uniformity across production units.
